April 4th in Carson is a mild, dry kind of day — 94 years of records put the average high at 69° with only a 14% chance of rain. But the date has seen its extremes: a scorching 98° back in 1989 and a bone-chilling 36° low in 1956.
Carson's all-time records tell the story of a city that rarely gets pushed to the edge — but it can happen. The thermometer hit 108° on September 26, 1963, and dropped to 24° in January 1937, while a single January storm in 1956 dumped 6.53 inches of rain in one day.
Carson is a year-round mild destination with surprisingly little seasonal swing — monthly highs range from just 65° in late December to 79° in late July and early August. If you're chasing warmth, aim for summer; if you want to dodge rain, avoid the final week of December, which is both the coolest and wettest stretch of the year.
